NOVELTY - Preparation of hollow fiber homogeneous ultrafiltration membrane wire involves adding 60-70 pts. wt. dimethylacetamide, 18-22 pts. wt. polyvinylidene fluoride, 10-15 pts. wt. polyvinylpyrrolidone, 6-10 pts. wt. polyethylene glycol, 0.5-3 pts. wt. graphene oxide, 0.5-3 pts. wt. carbon nanotubes, and 0.5-3 pts. wt. carbon fibers to stirring tank, stirring in oil bath at 50-100 degrees C to obtain casting solution, adding 30 pts. wt. dimethylacetamide, 30 pts. wt. glycerol and 40 pts. wt. water to container, stirring at 40-70 degrees C to obtain hollow medium, injecting the casting solution and the hollow medium into spinning device a extruding from the spinneret, subjecting to non-solvent induced phase separation method, forming the instantaneous functional layer in water coagulation bath, and heat-treating in 60-80 degrees C water bath for 0.5-2.5 hours. USE - Preparation of hollow fiber homogeneous ultrafiltration membrane wire (claimed). ADVANTAGE - The preparation method is economical and produces ultrafiltration membrane wire with excellent uniformity, high strength, elongation and production efficiency, excellent filtration effect, hydrophilicity and anti-fouling property, and prolonged service life.
